Abstract (en)
[origin: WO2021079331A1] A shaped abrasive particle is presented. The shaped abrasive particle has a first and second surface. The first and second surfaces are substantially parallel to each other and separated by a thickness. Each of the first and second surfaces have a surface profile, which includes a plurality of corners and a plurality of edges connecting the plurality of corners. The shaped abrasive particle also includes a recess included wholly within one of the plurality of edges, wherein the recess is a concave void extending into the surface profile. The shaped abrasive particle also includes a magnetically responsive coating. The magnetically responsive coating causes the shaped abrasive particle to be responsive to a magnetic field. The shaped abrasive particle, when exposed to the magnetic field, experiences a net torque that causes the shaped abrasive particle to orient with respect to the magnetic field such that each of the first and second surfaces are substantially perpendicular to a backing.
